CVE-2025-3535Public exploitNetwork attack vector

Application hang via unbounded database growth

Published Apr 13, 2025 · Updated Apr 14, 2025

Resource exhaustion in shuanx BurpAPIFinder 2.0.0 through 2.0.2 allows remote attackers to hang Burp Suite through web content. BurpAPIFinder continually appends intercepted API-path data to BurpApiFinder.db without retention limits or automatic cleanup. A user must visit or proxy attacker-controlled content containing high-volume junk requests; database growth makes Burp Suite extremely slow or unresponsive.
